RTM-1000 Remote Test Wireless
System. The RTM-1000 provides a wireless link between your calibrated
measurement microphone and audio analyzer.That means you can quickly
test multiple locations from the front row to the nosebleed seats in the time
it would take to haul long mic cables to just one spot.
• Wireless link between test microphone and audio analyzer allows faster, easier
measurement of large performance spaces
• Optional 48V phantom power supply works with any measurement microphone
• Non-companded transmission does not affect audio quality
The key feature of the RTM-1000 is that it defeats the compander on both
the receiver and bodypack transmitter.Wireless mic systems normally use
companding (compressing/expanding) to stuff more dynamic range
through narrow wireless channels. But companding can also add
coloration or distortion to the signal. The RTM-1000 defeats the
compander circuit, leaving the signal from mic to analyzer unchanged.
The RTM-1000 system includes a bodypack transmitter in a rugged cast
magnesium case with a mic stand mounting strap and a TA4F-to-XLR
adapter cable to accommodate most calibrated microphones. The
RTM-1000 receiver includes two detachable 1/4-wave antennas, and can
be rack-mounted with optional hardware.
RTM-1000 Transmitter is shown with the mounting strap and
cable adapter. (Microphone and mic stand not included)
